@mady111 @arainey @becca1 @

Answer 2

solve for n on the first one, solve for x on the second one

Answer 3

1.b
2.c

Answer 4

1 is not right it is going to be + or -, 2 will be no solution over the real numbers

Answer 5

ooh so one is no solution and number 2 is right number

Answer 6

1 is going to be + or - 7 because the square root of 49 is 7 and with a square root it also has to be plus or minus, and 2 is going to be no solution because 64 is negative. 3 is going to be postive 12 x because 12 is going to be the same length times width

Answer 7

number 5 you have to replace x and with 9 and -9

Answer 8

yeah

Answer 9

oky thx ill try it

Answer 10

yep no problem

Answer 11

so it will be like -9^2+9=103

Answer 12

@16shuston

Answer 13

no don't replace z with 9 only x. you are solving for z

Answer 14

oooh okay

Answer 15

yeah. Did you figure it out?

Answer 16

yeah z=22 right

Answer 17

yeah but it would be negative

Answer 18

-22?

Answer 19

yeah

Answer 20

thx @16shuston

Answer 21

yep no problem @meme106
